Analyses by Aengevelt Research show that the Frankfurt office market recorded office space take-up of approximately 177,000 square metres in the first half of 2026, including owner-occupiers. This figure represents almost a halving compared to the same period last year, when approximately 344,000 square metres were transacted in the first half of 2025. It also fell 18 per cent short of the decade average for the first halves of 2016 to 2025, which stood at an average of 215,500 square metres.
This decline is also evident in the national ranking: Frankfurt fell from first place in the previous year's period to fourth place among the office markets with the highest take-up, behind Berlin (380,000 square metres), Munich (355,000 square metres), and Hamburg (185,000 square metres).
Forecasts for 2026 and Stock Development
For the full year 2026, Aengevelt forecasts office space take-up of approximately 400,000 square metres in Frankfurt. This figure would be around 29 per cent below the previous year's result of approximately 564,000 square metres in 2025. It would also miss the ten-year average of around 486,000 square metres per year by approximately 18 per cent.
The supply reserve in Frankfurt, meaning the space available at short notice, also shows a significant trend. After falling from approximately 1,030,000 square metres in 2022 to around 940,000 square metres, it increased again to about 1,050,000 square metres by the end of 2023. According to Aengevelt Research, by the end of June 2026, the supply reserve further rose by approximately 13 per cent to around 1,390,500 square metres. Compared to the same period last year, end of June 2025, with 1,290,000 square metres, this represents an increase of approximately 8 per cent. The vacancy rate analogously increased from approximately 11.3 per cent at the end of June 2024 to around 11.6 per cent, with a total office space stock of approximately 12 million square metres. For the end of 2026, a slight increase in office space availability to around 1,420,000 square metres is expected.
Completions and Rent Development
The forecasted completion volume for 2026 is around 120,000 square metres. Although this would be double that of 2025 (around 60,000 square metres), this figure is approximately 12 per cent below the decade average of 136,400 square metres per year. Furthermore, crisis-related delays in completions are possible.
Notwithstanding the growing supply reserve, the prime rent in Frankfurt increased by 7 per cent to 55 EUR per square metre by the end of June 2026, compared to the same period last year (51.50 EUR per square metre at the end of June 2025). This reflects the continuously high demand for modern, ESG-compliant office spaces, which remain scarce in Frankfurt. An overall stable prime rent level is assumed until the end of 2026. The average rent in city centre locations also rose by 8 per cent to a current 33.50 EUR per square metre (end of June 2025: 31 EUR per square metre).
